No Signal for BIOS - Rx580

[solyomvari]

Hi,

I can't enter the BIOS. Straight to Windows LogIn screen show via HDMI. Windows work with HDMI. (GPU is from secound hand, but no minning)
Config: AMD Ryzen 5 5600X, MSI B550 Tomahawk (with latest BIOS update), 2x8GB Fury 3200MHz, Crucial P5 Plus 500GB, MSI Rx 580 Gaming X 8GB (
Version 015.050.002.001.000000)
- Hisense 55U8QF/Samsung (old 1080p capable).

i tried these: HDMI cable, HDMI output 1/2, CMOS reset, Windows>BIOS jump.

Try Display Port

Leave the GPU alone in the system in 1st PCI-E slot, [remove any other GPUs]
then retry.

If that works OK, then swap the places of the GPUs.
